A 24.2 KB PDF for part 2SC5287, an NPN transistor by Japanese JIS designation. Though tagged as a schematic, a part-numbered file like this is normally a datasheet…

Small 37.9 KB PDF for the 2SC4715, with an _E suffix in the name whose meaning is not stated, possibly a language or document edition marker.

Documentation for the 2SC4781 in a 120 KB PDF, indexed as a schematic though the name matches a discrete semiconductor part.

PDF reference for transistor part 2SC4428, 107 KB, indexed under the schematic category.

A 105 KB PDF covering the 2SC4426, filed as a schematic although the name is a component number.

PDF of 60.0 KB named 2SC5127, categorized as a schematic though it should be the device datasheet for that NPN bipolar transistor.

Only the part number 2SC5108 appears in the name of this 242 KB PDF, which is filed as a schematic but should be read as a transistor datasheet.

Compact 29.9 KB PDF for the 2SC5776, indexed as a schematic but named with a single semiconductor part number.

Part-number PDF for the 2SC4107, 93.2 KB, stored in the schematic category. Nothing in the name points to a specific device or board; the 2SC prefix marks an NPN bipolar…

A 31.3 KB PDF for the 2SC5764, stored with the schematics. The name contains just the semiconductor part number; in Japanese numbering, 2SC identifies an NPN transistor…

Named 2SC5569 and weighing 50.3 KB, this PDF sits in the schematic category but refers only to a transistor part number.

The 2SC5567 transistor is the subject of this 49.6 KB PDF, which the catalogue lists as a schematic.

A 129 KB PDF labelled 2SC5562, kept in the schematic section of the catalogue. The name holds only the part number; the 2SC prefix in JIS/JEITA naming identifies an NPN…

PDF of 472 KB describing the 2SC5085 component, an NPN transistor under the Japanese 2SC numbering scheme.

PDF document, 124 KB, named for the 2SC5886 part, an NPN bipolar transistor by its 2SC prefix.

Short 30.1 KB PDF for the 2SC5778 transistor, placed in the schematic category. Japanese JIS codes beginning with 2SC denote NPN bipolar devices, so the contents are…

Reference PDF for the 2SC5489, 31.3 KB in size and filed as a schematic. In the Japanese JIS convention the 2SC prefix identifies an NPN transistor, so the document is…

Brief 41.9 KB PDF for the 2SC5453, in the JIS 2SC range that denotes NPN transistors. Catalogued as a schematic, it is most plausibly a short datasheet covering the…

PDF sheet titled only with the part number 2SC5022, 42.0 KB, placed under schematics. No suffix, revision or maker appears in the name.

Specification PDF, 30.2 KB, for the 2SC3913 transistor. JIS part numbering assigns the 2SC prefix to NPN bipolar devices, so the document is most likely a datasheet…

A 99.4 KB PDF for the 2SC3779 transistor. The file name gives only the part number; the 2SC prefix follows the Japanese JIS scheme for NPN transistors, so this is almost…

Datasheet-style PDF for the 2SC5386 transistor, filed under schematics in this index. The 2SC prefix follows the old JIS convention for NPN transistors intended for…

PDF reference for the 2SC5378 transistor, with the _E tag likely marking an English version, about 35 KB in size.

A 100 KB PDF reference for the 2SC4919 transistor, catalogued as a schematic. The 2SC prefix follows the JIS convention for NPN bipolar transistors; manufacturer and…

Short 40 KB PDF named for the 2SC4913 transistor. The 2SC prefix marks an NPN bipolar device under JIS registration, and the name carries no further detail about maker…

The 2SC4909 NPN transistor is documented in this 61 KB PDF, listed under schematics but by its name a component datasheet.

The 2SC3689 transistor is the subject of this 89.7 KB PDF, which the catalogue lists as a schematic.

PDF document of 212 KB for the 2SC3620, filed under schematics but in practice a component datasheet for a discrete transistor.

Specification document for the 2SC3515 transistor, a 225 KB PDF placed in the schematic category.

Part number 2SC5354 is all the name reveals about this 129 KB PDF, so it is not tied to any identified device.

Transistor datasheet in PDF form, 188 KB, named 2SC5352 without any device or board reference.

Small 41.7 KB PDF for the 2SC5346; the _E suffix possibly marks an English edition, though the name alone cannot confirm this.

Compact PDF of 48.2 KB named after the 2SC3315 part number, catalogued as a schematic but most likely a datasheet for that discrete transistor.

Covering the 2SC3150 transistor, this 103 KB PDF sits in the schematic category of the index.
